Answer:
True: In binary search algorithm, we follow the below steps sequentially:
Input: A sorted array B[1,2,...n] of n items and one item x to be searched.
Output: The index of x in B if exists in B, 0 otherwise.
low=1high=n while( low < high ) { mid=low + (high-low)/2 if( B[mid]==x) { return(mid) //returns mid as the index of x } else { if( B[mid] < x) //takes only right half of the array { low=mid+1 } else // takes only the left half of the array { high=mid-1 } } }return( 0 )Explanation:
For each iteration the line number 11 or line number 15 will be executed.
Both lines, cut the array size to half of it and takes as the input for next iteration.

A pentagonal number is defined as
(n(3n1))/2
for n = 1; 2; ::: and so on. So, the first few pentagonal numbers are 1; 5; 12; 22; :::
Write the following method that returns the nth pentagonal number:
public static int getPentagonalNumber( int n )
Answer:
public static int getPentagonalNumber( int n ){
//initialize the variable
int NthpentagonalNumber;
// use formula
NthpentagonalNumber = n*((3*n)-1)/2;
//return the result
return NthpentagonalNumber;
}
Explanation:
Create the function with return type int. it means, the function returns the integer value to the calling function.
In the function, we declare the one parameter with an integer type. so, it takes the value from the calling function.
then, initialize the variable for storing the output.
the formula for calculating the pentagonal number is:
[tex]pentagonal number = n*(3n-1)/2[/tex]
the value is passed by the user and the function capture the value in the parameter and then use the formula to store the output the variable.
and finally, return the output.

The factorial of a number n, written in math as n!, is the product of all the numbers from 1 to n or 1*2*3* … *n. Write a C++ program that requests a number from the user and then displays the factorial of that number. The program should only accept positive integers greater than 0.
Answer:
#include <iostream>
using namespace std;
int main()
{
int factorial=1;
int num;
cout<<"Enter any Number: ";
cin>>num;
for(int i=1;i<=num;i++){
factorial=factorial * i;
}
cout<<"The factorial of the number is "<<factorial<<endl;
return 0;
}
Explanation:
Create the main function and declare the variable.
then, print the message by using the cout instruction.
store the value enter by user in the variable.
After that, take a for loop from 1 to user value both are included.
and multiply the value with previous value and it happen until the condition in the loop true.
for example:
i=1
fact = 1*1=1
i=2
fact = 1*2=2
i=3
fact= 2*3=6 and so on....
finally print the result.
A C++ program to calculate the factorial of a positive integer uses a loop to successively multiply the numbers from 1 up to the input number. The program checks that the user input is a positive integer since the factorial is only defined for non-negative integers.
Explanation:C++ Program to Calculate FactorialTo calculate the factorial of a number in C++, we can ask the user to input a positive integer and then calculate the factorial by multiplying all the integers from 1 up to the number provided. The factorial of a number n, written as n!, is the product of all positive integers less than or equal to n. Below is a simple C++ program that calculates the factorial:
#includeThe program uses a loop to repeatedly multiply the factorial variable by each number up to the input number. We use an unsigned long long for the factorial variable to handle potentially large numbers, although there is still a limit to how large a number this data type can store. The program also includes a basic check to ensure that a negative number is not input, as factorials are only defined for non-negative integers.
A trust domain is defined as Select one: a. The agreed upon, trusted third party b. A scenario where one user needs to validate the other’s certificate c. A construct of systems, personnel, applications, protocols, technologies, and policies that work together to provide a certain level of protection d. A scenario in which the certificate’s issuer and subject fields hold the same information
Answer:
A construct of systems, personnel, applications, protocols, technologies, and policies that work together to provide a certain level of protection
Explanation:
Creation of dynamic Trust Domains can be realized through collaborative, secure sharing solutions. The local system is able to trust a domain to authenticate users. If an application or a user is authenticated by a trusted domain, all domains accept the authenticating domain. For instance, if a system trust domain X, it will also trust all domains that domain X trusts. It is a two-way trust relationship and is transitive.
Answer:
A construct of systems, personnel, applications, protocols, technologies and policies that work together to provide a certain level of protection
Explanation:
A trust domain is a certificate that entities or users gain and is granted by a trusted domain this is that when you enter another software or other systems you will be recognized as a trusted character or user and gives protection between systems and softwares and provides protection for the users.

Failing to include a complete ____ on each side of an && operator in an if statement is a common error in Java programming.
a.
operator
b.
mathematical expression
c.
variable
d.
Boolean expression
Answer:
Boolean expression
Explanation:
The operator '&&' is called AND operator. it provide the output base on the Boolean value on each side of AND operator.
it has four possible values:
First Boolean is TRUE and Boolean is TRUE, then result will be TRUE.
First Boolean is TRUE and Boolean is FALSE, then result will be FALSE.
First Boolean is FALSE and Boolean is TRUE, then result will be FALSE.
First Boolean is FALSE and Boolean is FALSE, then result will be FALSE.
Therefore, the correct option is Boolean expression.
Write a function that converts a C-string into an integer. For example, given the string “1234” the function should return the integer 1234. If you do some research, you will find that there is a function named atoi and also the stringstream class that can do this conversion for you. However, in this program, do not use any predefined functions and you should write your own code to do the conversion. Use the function in your C++ program
What does it mean to catch an exception?
Answer:
An exception is an event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions. When an error occurs within a method, the method creates an object and hands it off to the runtime system. ... This block of code is called an exception handler.

Which of the following does Moore's law predict?
a.The power of microprocessor technology doubles and its cost of production falls in half every 18 months.
b.The cost of microprocessors will increase as their power increases.
c.The price of microprocessors continues to fall, while their cost of production increases.
d.The demand for microprocessors continues to rise, while their supply falls.
e.The demand for microprocessor technology falls in half every 18 months.
Answer:
Hi!
The correct answer is the a.
Explanation:
The Moore's law is an a empirical law that Gordon Moore predicted doing some observations about how the density of the transistors on a integrated circuit was increasing over time.
For example, this law state that if you have an integrated circuit with: 1000 transistors in 1980 then in 1981 and six months later you will have the same integrated circuit with 2000 transistors, and so on..
Jan 1980: 1000 transistors.Jul 1981: 2000 transistors.Jan 1983: 4000 transistors.Jul 1984: 8000 transistors.And that's the reason because its cost will fall too.

Decision variables reflectthe level of effectiveness of a system.
True
False
Answer: False
Explanation:
Decision variables does not reflect the level of effectiveness of a system as, decision variable are directly controlled by decision controller, and there are components that there value can be undetermined for the decision controller. All the mathematical equations defined the accurate relationship between the variable of the system and the measurement of the system effectiveness. Decision variables are basically referred as the basic objective and the constraints list.
Which Numpy function do you use to create an array? (Points : 1) np
np.array
np.numpy
numpy
Answer:
The correct option is np.array
Explanation:
Numpy is a library to perform numerical calculation in python. It allows us to create and modify vectors, and make operations on them easily. Numpy arrays are an excellent alternative to python lists. Some of the key advantages of numpy arrays are that they are fast, easy to work with, and offer users the opportunity to perform calculations through full arrays.
To start using numpy, the library must be imported:
import numpy as np
The most common way to create a vector or matrix already initialized is with the np.array function, which takes a list (or list of lists) as a parameter and returns a numpy matrix. The numpy arrays are static and homogeneous typing. They are more efficient in the use of memory.
Example:
list = [25,12,15,66,12.5]
v = np.array (list)
print (v)
True of False - use T or F An abstract class can have instances created using the constructor of the class.
Answer:
False
Explanation:
An instance of an abstract class cannot be created through the constructor of the class, because it does not have a complete implementation. Though, it is possible to have references of an abstract type class. Abstract classes are incomplete structures and you would have to build onto it before you are able to use it.
______ is the ability of a system to do more than one thing at a time. A. Multibusing c. online processing b. Multiprocessing d. Batch processing
Answer:
Multiprocessing.
Explanation:
In multiprocessing the system uses two or more processors to do more tasks simultaneously.
The ability of a system to do more than one thing at a time, known as multiprocessing, allows for the concurrent execution of multiple tasks by using multiple processing units or cores.
Explanation:The ability of a system to do more than one thing at a time is known as multiprocessing. Multiprocessing systems have multiple processing units, commonly referred to as cores, which can execute tasks simultaneously. Unlike single-core systems, which can only handle one operation at a time, multiprocessing systems can perform multiple tasks concurrently, improving overall system efficiency and performance.
In the context of computers and operating systems, this capability allows a computer to run different processes at the same time, such as running a web browser while also running a spreadsheet application or virus scan. The operating system manages these processes and allocates processor time in such a way that users experience the tasks as though they are happening simultaneously.
By contrast, multibusing refers to a system where multiple buses allow many devices to connect and communicate with the CPU at the same time, while online processing is processing that is active and connected to a network. On the other hand, batch processing is a method of processing data in which transactions are collected and processed all at once at a particular time.
What is the output of the following program segment?
int x = 0;
++x;
x++;
++x;
x++;
++x;
Answer:
5
Explanation:
The operator 'x++' is called the post increment operator, it is assign first and then increment.
The operator '++x' is called the pre increment operator, it is increment first and then increment.
So, both are increment operator which increment the value by one.
initially the value of x is zero,
++x increase the value to 1 and than assign to x.
then, x++ it assign to x first then increment by 1 means x=2
and so on.....
Their are five increment operator are used. so, the result is 5.
The operation ____ is used to remove the top element from the stack.

System.out.println(num);
counter+=1;
}
System.out.println(counter+" data values were read");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Solve the following system of algebraic equations: Y = 1-x^2 and y = 1+x
Answer:
x=0; x=1
Explanation:
The system presents a quadratic equation and a linear equation. Therefore, the result will have two solutions.
The first step is to match the two equations:
[tex]1+x=1-x^{2}[/tex]
Then we clear the equation by zeroing.
[tex]0=x^{2} +x+1-1[/tex]
Now we perform indicated operations
[tex]x^{2} +x=0[/tex]
We factor with the common factor method
x(x+1)=0
We equal each factor to zero and get the results
x=0
(x+1)=0
x=-1
The two values that satisfy both equations are 0 and -1
Write a program that will compare two names. The program prompts the user to enter two names for a comparison. If the names are same, the program states that. If the names are different, the program converts both names to UPPERCASE, and compares then again. If they are equal, the programs displays a message stating that names are equal if CASE is ignored. Otherwise, the program prints names with a message that names are not equal.
Answer:
We can use comparison operator 'Equals to' (==) to compare two strings.
Explanation:
We can use conditional statement 'if else' to put conditions. If statement contains boolean expression.If statement is followed by else block. If the boolean expression evaluates to true, then the if block of code is executed, otherwise else block of code is executed.
If we want to compare two strings with uppercase, then we can convert the input strings given by users using ToUpper() string function.
For example,
string abc;
string uppercase= abc.ToUpper(); // gives ABC as result

What is the data rate of a DS0 signal?
Answer: 64 Kbps
Explanation:
The governor of New York that he has directed the state's Division of Criminal Justice Services to gather DNA from the broadest range of convicted criminals permitted under current law. This will result in the collection of as many as 40,000 DNA profiles. The additional DNA profiles may be obtained as a condition of release on parole or probation, as a condition of participation in the Department of Correctional Services' temporary release programs, and as a condition of a plea bargain. This _____ will be used for solving crimes.
database
network
mainframe
combination
conglomerate
Answer:
Database
Explanation:
Database.
The State’s DNA database is a database of DNA profiles that can be made public or private and can be used in the analysis of genetic fingerprinting for criminology. There are certain laws that come with how DNA databases are supposed to be handled.
Final answer:
The correct answer is "database". The additional DNA profiles directed by the New York governor will be added to a database and used for crime solving. This database, part of CODIS, facilitates forensic DNA analysis to match suspects with evidence, exonerate the innocent, and help solve crimes. The expansion of DNA collection in criminal justice raises important discussions regarding legal and privacy concerns.
Explanation:
The governor of New York has initiated an expansion of DNA collection to include the broadest range of convicted criminals allowed under current law, potentially adding up to 40,000 DNA profiles to the database. Such a database is crucial for the enhancement of law enforcement capabilities, allowing for the solving of crimes through forensic DNA analysis. This database is part of a larger system known as CODIS (Combined DNA Index System), which is maintained by the Federal Bureau of Investigation (FBI) and plays a vital role in criminal justice by matching DNA from crime scenes with potential suspects, exonerating the innocent, and providing leads in cold cases. The unique nature of DNA makes it an incredibly powerful tool, as the statistical power of discrimination from DNA analysis is profound, often making the probability of coincidental matches incredibly slim.
The use of DNA evidence in the legal justice system is not without its controversy, as questions around privacy and the extent of DNA collection arise. However, legal precedents such as State v. Franklin and U.S. v. Mitchell support the practice of taking DNA swabs even when individuals are only arrested, not convicted, under certain conditions. Additionally, the technology has proven beneficial, as evidenced by the work of the Innocence Project, which has used DNA fingerprinting to free wrongly accused individuals. DNA profiles in CODIS contribute to this by facilitating the identification of the true perpetrators and preventing miscarriages of justice.

Unlike the climate of the other islands of Hawaii, ________Kona contains 54 different temperate zones.
that of
this is
these are
those that
Answer:
None
Explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Unfortunately, none of these answers would be factually nor grammatically correct. For Starters Kona is not an island Kailua-kona is the capital town of the Big Island in Hawaii.
Regardless of that fact, none of the answers given would make the sentence make sense grammatically. The Only way for the sentence to make sense grammatically, the answer either needs to stay blank or be Kailua. Like so...
Unlike the climate of the other islands of Hawaii, Kailua Kona contains 54 different temperate zones.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
The sentence should be completed with 'that of,' making it read 'Unlike the climate of the other islands of Hawaii, that of Kona contains 54 different temperate zones.' Hawaii's diverse climates are heavily influenced by altitudinal variations and topographical features, leading to a range of climatic zones across its islands.
The correct completion for the sentence provided is that of. Hence, the complete sentence reads: Unlike the climate of the other islands of Hawaii, that of Kona contains 54 different temperate zones.
Hawaii is known for its diverse climate conditions. While most islands in the Pacific have a tropical type A climate, Hawaii has a variety of climatic zones due to its topography and altitudinal variation. For instance, Kauai, one of the Hawaiian Islands, is one of the wettest places on Earth, receiving more than 460 inches of rain per year. This high level of precipitation is due to the rain shadow effect caused by Mt. Wai'ale'ale. The windward side of this mountain receives substantial rainfall while the leeward side remains semi-desert due to the rain shadow.
Japan, another island group, also presents diverse climates. One of its islands, Hokkaido, features a type D climate and is known for snowfall that supports activities like downhill skiing. Japan's diverse climate is a result of its mountainous terrain, with active volcanoes like Mount Fuji influencing the regional climate conditions.
